Function:
Like a building you have a inner framwork, but it is made up of bones instead of steel. The number of bones in your skeleton depends on your age. A newborn baby has about 275 bones. An adult , however, has about 206 bones. A baby grows some of its bones fuse together. For example, as a baby, you had many more individual bones in your skull than you do now.
Five major functions:
It provides you support, makes you move, portect your intrenal organs, produces blood cells, and stores certain materials untill needed.
Skeleton: Your skeleton determines the shape of your body, much as a steel frame determines in the shape of a building. The backbone, or vertebral column, is the center of the skeleton. Notice that all the bones of the body are in some way connected to this column. If you move your fingers down the center pf your back, you can feel the 26 small bones, or vertebrae (signal vertebrae), that make up your backbone. Bend forward at the waist and and feel the bones adjust as you move. You can think of each individual vertebra as a bend on a string. Just as a beaded neckless is flexible and able to bead, so too is your veratbral column. If backbone were just 1 bone, you would not to be able to bend or twist.
Muscles: Some of your body's movement, such as smiling, are easy to control. Other movements, such as the beating of your heart, are impossible to control. That is because some muscles are not under you conscious control. Those mucles are called involuntary mucles. Involuntary mucles are responsible for activies such as breathing and digesting food. Types of Muscles: Your body has three types of tissue - skeletal muscle, smooth muscle, and cardiac muscle. Both skeletal and smooth muscles are found in many places in the body. Cardiac muscle is found only in the heart. Each muscle type perfroms specific functions in the body.
